Should you seal old concrete?

Should I pressure wash concrete before sealing?
Pressure-washing usually isn’t enough to thoroughly remove previous coatings or contaminants and adds unneeded moisture to the concrete. It’s better to use mechanical means, such as grinding, mechanical scarifying or blasting, to make sure the concrete surface is completely clean and dry before you apply a new sealer.
